The reason why I always catch a cold
There are many cold symptoms, common cough, runny nose, sneezing, fever, etc., many cold after grape treatment will be good. But some of the things that need to be paid attention to are the symptoms of colds. In fact, other diseases may also be hidden. If the situation is serious, it is the precursor symptoms of some malignant diseases.
Experts said that the early symptoms of acute nephritis, influenza, allergic rhinitis, pneumonia, leukemia, lupus erythematosus and other rheumatic diseases and encephalitis may be similar to those of the common cold. Therefore, the cold is still not cured after more than a week, or there is no effect after taking the common cold medicine, so it is necessary to carefully observe and identify, so as not to delay the disease by mistaking the common cold treatment.
1. Acute nephritis
Symptoms: prodromal symptoms also have upper respiratory tract inflammation and tonsillitis
Identification: whether there is edema, decreased urine volume, urine change 'meat washing water' color
Liang Jianbo, director and chief physician of Nephrology Department of the Second Affiliated Hospital of Guangzhou Medical University, said streptococcus infection is the main cause of acute nephritis. Its prodromal symptoms are upper respiratory tract inflammation and tonsillitis 2-3 weeks before the onset of the disease, manifested as sore throat, runny nose, nasal congestion, and may also have a fever. These symptoms are very similar to the common cold and can be easily treated as a common cold.
A considerable part of acute nephritis is caused by upper respiratory tract infection. "However, acute nephritis still has some specific symptoms different from the common cold. First, it may cause edema in the legs and lower limbs; second, it may reduce urine volume; third, the color of urine will change to the color of" meat washing water ", that is, hematuria. Therefore, if these three symptoms appear after a cold, the patient must go to the hospital for a routine urine test to see if there is proteinuria and hematuria, or a blood biochemical test to see if there is a transient increase in serum creatinine. '
In addition, acute nephritis may be accompanied by anorexia, fatigue, nausea and vomiting, Liang said.
2. Influenza
Symptoms: at the initial stage, there are nasal congestion, runny nose, sneezing, cough and other nasopharyngeal symptoms
Identification: obvious systemic symptoms, persistent high fever, ineffective common cold drugs, group onset
Xu Pusheng, director of the outpatient department of the Second Affiliated Hospital of Guangzhou Medical University and chief physician of respiratory medicine, said that the initial symptoms of influenza are similar to common cold, and nasopharynx symptoms such as nasal congestion, runny nose, sneezing and cough can also appear.
But flu is different from the common cold in symptoms and infectivity. Xu Pu Sheng said: first, the common cold mainly has nasopharyngeal symptoms, while influenza has mild nasopharyngeal symptoms and obvious systemic symptoms, including fever or chills, fatigue, etc., which are more severe than the common cold; second, there is usually a persistent high fever; third, the common cold can be cured in about a week, and the course of influenza may be longer, so the effect of taking common cold medicine is not obvious; Fourth, influenza is highly contagious. It always occurs in a family, an office, a class or even a school.
Therefore, if the symptoms of a cold have the above four characteristics, we should be alert to whether it is influenza, especially when taking common cold medicine is ineffective, we should seek medical advice in time. 'said Xu.
3. Allergic rhinitis
Symptoms: there will be sneezing, runny nose, nasal congestion and other symptoms
Identification: clear water in the morning, sensitive to pungent odor
Sneezing, runny nose and stuffy nose are common features of allergic rhinitis. Xu said that many patients with allergic rhinitis when cold treatment, the results, the more treatment, the worse the effect.
Xu Pu Sheng said that compared with the common cold, allergic rhinitis has more serious nasal symptoms, mainly with the following characteristics: first, it will generally clear the nose in the morning, itchy nose, some patients will be accompanied by itchy eyes and tears; second, it will sneeze and yawn when encountering irritating smell; third, the effect of taking antiviral drugs is not obvious; fourth, it generally does not have fever, no body ache and other symptoms.
Xuposheng reminds, cold is caused by virus, allergic rhinitis is caused by pollen, fungal spores and other allergens. Allergic rhinitis with antiviral effect is not obvious, but need to use anti allergic drugs.
4. Pneumonia
Symptoms: there will also be high fever, cough and other symptoms
Identification: high fever, cough yellow sputum or rust colored sputum
Lobar pneumonia is a kind of acute pulmonary inflammation caused by Streptococcus pneumoniae. There will also be high fever, cough and other symptoms similar to the common cold.
Xu said that this kind of pneumonia is easy to occur in the elderly with low resistance, children and middle-aged and young people with excessive fatigue. Compared with the common cold, this kind of pneumonia has the following characteristics: first, high fever does not subside; second, cough yellow sputum, severe cough rust colored sputum; third, chest pain may appear.
Therefore, when children, the elderly and the middle-aged and young people with excessive fatigue catch a cold, we must carefully observe and go to the hospital in time.
Advice on always catching a cold
1、 Prepare cold medicine
Home prepared painkillers such as ibuprofen, acetaminophen and aspirin are known to treat colds. Although there are all kinds of cold medicines on the market, they are basically the above ingredients. Whether you choose tablets, capsules, a soluble tablet or a cup of powder, this is the best way to treat a cold.
2、 Prepare decongestants
Decongestants can help people clean up the sinuses and relieve the symptoms of nasal congestion and poor breathing caused by cold. Most of the drugs for the treatment of cold and influenza have certain decongestant components, which can play a refreshing effect. But if you want to rest, try not to take it in advance, because the exciting ingredients in the drug may not make you fall asleep so easily.
3、 Supplement zinc
A recent study has shown that taking zinc syrup, tablets or lozenges can reduce the symptoms of cold patients and accelerate the recovery time of cold. However, the use of this method should be very careful, because long-term use may cause adverse side effects such as vomiting and diarrhea.
4、 Always check your medicine box
You should always check your own medicine box to see if there are expired drugs in it, or the effect of drug resistance. In addition, we should also pay attention to whether the cold medicine you take has adverse reactions with other drugs you are taking now. If you have any questions about this, please ask your doctor for help.
5、 Try not to use antibiotics
Usually, everyone's cold is almost caused by virus infection, and the use of antibiotics will never reduce the symptoms of a cold. On the contrary, overuse of antibiotics can increase the resistance of bacteria in the body to antibiotics, so antibiotics can not be used unless you really need them.
6、 Put humidifier in front of desk
Humidifier can make your working environment more humid. Breathing in steam can help you wet the mucus in your nose and make it easier to blow it out. If you work in an office, put a basin of hot water on your desk or an air humidifier.

2. Lentinus edodes
Regular consumption of Lentinus edodes can promote metabolism, make people energetic and not easy to catch a cold. Through research, scientists found that Lentinus edodes contains mushroom ribonucleic acid, which can stimulate human reticular tissue cells and leukocytes to release interferon, and interferon can eliminate the virus in the human body, and then strengthen the human body's resistance to influenza virus. In addition, Lentinus edodes has the function of eliminating virus activity.
3. Tomatoes

Vitamin C can not only fight against diseases, but also relieve some serious cold symptoms and shorten the course of disease. But taking a vitamin supplement is not the only choice; the delicious and omnipotent red peppers contain twice as much vitamin C as oranges, and they can be added to many dishes.
5. Sweet potato
It is suggested that you only need to eat a sweet potato of moderate size every day to absorb the vitamin C content that the human body needs in a day; and the vitamin C in sweet potato is more heat-resistant than that in other foods.
